GRAIN-DRILL.

Specification of Letters Patent.

Patented Sept.'3, 1912.

Application filed August 20, 1909. Serial No. 513,885.

To all whom it may concern:

Be it known that we, CLARENCE A. PATTI- SON and LUTHER E. RoBY, citizensof the United States, residing at Peoria, in the county of Peoria andState of Illinois, have invented certain new and useful Improvements inGrain-Drills; and we do hereby declare that the following is a full,clear,

and exact description of the invention,

which will enable others skilled in the art to which itappertains tomake and use the same.

This invention has reference to certain new and useful improvements ingrain drills, and relates particularly to the mounting for the shank andshoe or runner inconnection with the disk with which they are associatedand with which they cooperate.

One of the objects of the present invention is tov combine with a diskfurrow opener, a shank having a combined runner and scraper, thefunction of said runner and scraper being to follow in the furrow cut bythe disk, that the seed may be deposited at the deepest point of thefurrow,-

and further to cooperate with the convex face of the disk to scrape thesame, if such is desired, a compression and torsion spring serving toboth normally retain the shank and shoe in its normal depressed positionand to hold the forward portion of the shoe in contact with the face ofthe disk.

The invention'has for a further object to support a seed tube adjacentthe disk, with the shoe or runner of the tube preferably unattached; thesaid tube capable of vertical movement in its support, independent ofthe disk, whereby when the disk isforced into the ground to open thefurrow, said tube with its shoe or runner may automatically raise andlower, that the shoe or runner will ride in the furrow out by the disk.

The invention consists further, in the provision of details moreparticularly set out in the following description, claimed in theappended claims, and illustrated in the accompanying'drawmgs, in which-Figure 1 is a side elevation, partly in section, showing ourimprovements in grain drills; Fig. 2 is a rear elevation of the shankand support and guide therefor; Fig. 3 is a partial plan andcross-section as the same would appear on the line 3-3 of same wouldappear on the line 4-4 of Fig.

1; Fig. 4 is a cross-section in plan as the 1, and Fig. .5 is across-section in plan as the same would appear if taken on the line 5-5of Fig. 1.

Like numerals of reference indicate corresponding parts throughout thefigures.

In the drawings 6 denotes av draw-bar of the usual or approvedconstruction, which may be mounted or attached to the'frame orothersuitablep'arts of a drill in any desired manner. To the inner endof the draw-bar is j ournaled, in any suitable manner, a disk furrowopener 7. Said disk is preferably connected to the draw-bar so that 1tscutting edge is disposed diagonally to the line of draft, as seen inFigs. 3, 4 and 5.

To the bearing of the disk or disk support, on the concave or furrowside of the disk, is attached the forward end of an arm or frame 8. Thisarm is carried slightly up- Wardly and rearwardly and at the rear of thedisk is offset laterally and formed with a semi-circular barrel section9 having ears 10, to which may be bolted or otherwise secured,

similar cars 11 of a semi-circular barrel section 12. Uniting thesections 9 and 12 forms a barrel or socket, the axis of which is convexface of the disk and preferably following in the line of draft of thedisk, as shown in Figs. 3, 4 and 5. The upper forward portion of theshoe and scraper 15 is bent to conform to the surface of the con-' vexface of the disk and is unattached at its forward end, as shown in Fig.1.

The shank or seed tube 13 is placed in the half section 9, with acompression and torsion spring 17 coiled about the shank, as shown inFig. 1, with one end of the spring attached to a lug 18 on the shank andits opposite end attached to the section 9, whenthe section 12 may besecured to the section.

9, inclosing a portion of the body of the shank in the barrel, togetherwith the spring,

and yet allowing the shanle to have vertical movement in the barrel.The'spring 17 norwhich reference has been made, has its peculiaradvantage in machines of this type,

- when it is considered that the shoe or runner of said tube is totravel in the furrow cut by the disk. Todepress the disk and tube, toforce the disk into the ground-to open the furrow, they both oscillateor swing on the pivot of the draw-bar 6. It will be observed that thetube will swing on alonger radius than the disk, and that therefore ifthe tube could not move vertically in its support the device would failin the particular use for which it is intended, and that is, to have-theshoe always in the furrow cut by the disk; as it is, when the disk isforced into the ground, the shank or seed tube with; the verticalmovement of which it is capable, will automatically adjust itself to keethe shoe in the furrow, the spring 17 yieldin gly holding the tubeandshoe to their positions.

To the barrel may be attached a spring lift ro-d 19 for depressing thedisk to a suitable depth in the ground which will carry with it theshank and shoe andIScraper to follow in'the furrow formed by the diskdepositing the seed in the deepest portion of the furrow cut by thedisk; said rod being used also for elevating the parts of the ground.
